Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have drying function besides grinding.

depending on the coal application, have been experienced since the mill grinding capability is directly proportional to available grinding force. This implies, for example, that only six (6) or seven (7) mills of the same physical size are required today for a boiler that previously needed eight (8) mills to supply the same coal flow.

The coal flow into the mill is only indirectly mea- surable. Implying that the early fault detection based on detection of drops in the coal flow of the coal mill, is not so simple as it seems. A critical example on a fault in the coal mill is caused by a blocking in the raw coal inlet pipe, a coal mill is illustrated in Fig. 1.

Phrase one: raw material crushing Coal blocks will be crushed to 15mm-50mm fineness by crusher. Phrase two: drying and grinding 1.Coal material with low moisture will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding. The hot air in the mill will dry the coal. This will reduce drying cost. 2.For high …
